The York County Astronomical Society (YCAS) will host a public Starwatch at its observatory at John C. Rudy County Park, 400 Mundis Race Road, York, on Saturday, March 11, from 8 to 10 p.m. The event is free and open to the community.

The event will begin with a screened astronomical presentation on the James Webb Space Telescope's first images and other current astronomy topics. Guests will then be guided on a tour of the sky through one of the club's telescopes. Attendees will be shown a host of celestial objects, including Jupiter and Mars.

Visitors are also invited to bring their own telescopes to receive assistance with using them. YCAS members will be on hand to answer questions.

The event is free, but donations will be accepted. If the weather is clear, all activities will occur as scheduled. In the event of extreme weather, call 717-759-9227 for notice of cancellation or visit http://www.astroyork.com or search for "York County Astronomical Society (YCAS)" on Facebook.
